reading from a serial port (boot)

[mixo]

My serial port permission look like this:

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
crw-rw----    1 root     uucp       4,  64 Dec 11 07:54 ttyS0
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Now I have a script that starts up as the machine boots and
read from the serial port. My problem is, it does not get
anything from the port, unless I manualy start it as 'root'.
What do I need do /change to get it to start reading at
boot time?

P.S
     The script to start the daemon has the following  permissions
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
-rwxr-xr-x    1 root     root         1463 Dec 10 17:29 myscript.sh
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

     The daemon itself,
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
-rwxr-xr-x    1 root     root         3678 Dec 10 16:04 mydaemon.py
